    摘要: A tire bead assembly of a bead core, apex and gum tie strip is made by laying the gum tie strip about a non-inflatable annular member of triangular cross-section and across the slant surface of the member. The apex is wrapped then about the tie strip and about the slant surface of an annular inflatable bag. After the core is pressed coaxially on the tie strip so as to indent the member and thus preform the tie strip, the bag is inflated to turn the apex and underlying tie strip about the core and against an annular forming member to shape the assembly suitably for the tire carcass in which it is to be inserted. A bladder is then inflated to wrap the tie strip on the second side of the core and apex. The member bridges the gap between the adjacent edges of the bag and the bladder. An apparatus for carrying out the steps is also described. The resulting bead assembly is tightly cohered and free of wrinkles and air pockets. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

    摘要: An annular wedge suitable for use in a tire bead assembly preparation apparatus. The annular, resilient, flexible, compressible wedge has a generally T-shaped axial cross-section with an outer head portion, an inner trunk portion and an inner-connecting throat portion with a generally triangular cross-section therebetween, and a continuous reinforcing annular textile fabric strip integral with said head, throat and trunk portions, said wedge being of a continuous structure having a core of especially prepared microcellular polyurethane and an outer densified relatively smooth skin.
